Miniature rose plant named ‘KORpot106’

ABSTRACT

A new and distinct variety of miniature rose plant, referred to by its cultivar name, ‘KORpot106’, is disclosed. The new variety forms abundantly on a substantially continuous basis attractive, hot pink colored blossoms. Attractive vigorous vegetative is formed, which contrasts beautifully with the blossoms. The growth habit is compact. The new variety is well suited for providing attractive ornamentation in the landscape.

Botanical/commercial classification:

Latin name: Rosa hybrida.

Varietal denomination: ‘KORpot106’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right ApplicationNumber 2020/2367, which was filed at Community Plant Variety Office inthe European Union on Sep. 27, 2020, the contents of which are herebyincorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Miniature Rose Plant of the presentinvention was created during 2015 at Offenseth-Sparrieshoop, Germany byartificial pollination wherein two parents were crossed which previouslyhad been studied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., seed parent) of the newvariety was the ‘KORpot064’ variety (U.S. Plant Pat. No. 29,042). Themale parent (i.e., pollen parent) was an unnamed seedling(non-patented).

The parentage can be summarized as follows:‘KORpot064’ x unnamed seedling

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of rose plant of the present inventionpossesses the following combination of characteristics:

-   -   (a) displays attractive, hot pink colored blossoms,    -   (b) exhibits a compact growth habit, and    -   (c) forms vigorous vegetation.

The new variety well meets the needs of the horticultural industry. Itcan be grown to advantage as ornamentation in parks, gardens, publicareas, and in residential settings. Accordingly, the plant isparticularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguishedfrom its ancestors. More specifically, the ‘KORpot064’ variety (i.e.,the seed parent) displays less bright pink flower color and a lesscompact growth habit compared to the new variety. In addition, theunnamed seedling male parent (i.e., the pollen parent) displays lesscompact growth habit compared to the new variety and the new variety hasan improved shelf life compared to the pollen parent variety. Moreover,the new variety can be readily distinguished from other similarnon-parental varieties. For example, the ‘KORdatiffi’ variety(non-patented) displays less bright pink colored flowers and formsblooms in a cluster, whereas the new variety displays brighter pinkcolored flowers and forms blooms solitarily.

The new variety has been found to undergo asexual propagation in KleinOffenseth-Sparrieshoop, Germany by a number of routes, such asvegetative cuttings. Asexual propagation techniques in Germany, such asvegetative cuttings, have shown that the characteristics of the newvariety are homogeneous, stable, and strictly transmissible by suchasexual propagation from one generation to another. Accordingly, the newvariety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘KORpot106’.

The new variety was first offered for sale on January, 2020 by theinventor or another who obtained the new variety directly or indirectlyfrom the inventor.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonablypossible to make the same in color illustrations of this character, atypical specimen of the new variety. The illustrated rose plant of thenew variety was approximately twelve weeks of age and was observed atOdense, Denmark while growing indoors on its own roots in a 10.5 cmcontainer.

Drawing—illustrates a specimen of a plant displaying floral buds andflowers at varying points of opening.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart, 1966 edition). Theterminology which precedes reference to the chart has been added toindicate the corresponding color in more common terms. The descriptionis based on the observation of a one-year-old specimen of the newvariety, observed during October, while growing in a one-galloncontainer on its own roots in a greenhouse in Cochranville, Pa.
